rtAN'r-srnAYING MACHINE.

Application filed August 31, 1923. Serial No. 660,307.

plants may be sprayed with a mixture of Paris green or arsenate of lead together with a desirable amount water for exterminating the insects that gather upon said plants and greatly damage thefpsame. ,Y

The primary object of my invention is to provide suoli a machine .wherein the component parts thereof may be mounted in a novel and simple manner upon an unused cultivator or other desirable type of wheeled support the device comprising relatively few parts and these co-related in such a manner ras to reduce the Vpossibihty yof disarrangement yto minimum. y

A still further object of my invention resides in the provision of such a plant spray-y ing machine wherein the same includes a fluidltank which is to be charged with compressed air for discharging the contents thereof whenever the control valve is opened.

Another object is the provision of suoli a machine wherein the saine embodies a plui'ality of spraying nozzles arranged in pairs for permittinga multiplicity of rows of plants to be sprayed with the materialsimultaneously, means being also provided for adjusting these nozzles laterally of the machine for bringing the nozzles into positions directly above the plants to be sprayed.

An additional Objectis to include in the fluid tank a novel form of scraping means under the control of the operator of the machine whereby the Paris green or arsenate of lead that settles to the bottom may be sprayed therefrom. y

Other objects of this invention will become apparent as the nature of the same is better understood the invention comprising the novel form, combination and arrangement of parts set forth in the following specification, shown in the accompanying drawings and claimed.

In the drawings'wherein like reference characters indicate corresponding parts throughout the several views.`

Figure lis a side elevational view of improved machine,

Figure 2 is an elevational view of the sprinkler elements removed from the machine, n v Y Figure 3 is an enlarged detailY cross sectionthrough the fluid tank7 and Figures is an enlarged fragmentary section through one of the spraying nozzlesr per se.

Now having particular reference to the drawings, 5 designates the platform supported upon a cross axle 6 upon the opposite ends of which are supporting wheels 7.l EX- tending longitudinally and supported above said platform by brackets 8 is a rearwardly directed platform 9 upon the rear end of which is an operators seat 10, the front end of this platform 9 carrying a desirable form of draft appliancer 11. The construction just -set forth forms parts of well known cultivators and it is desirable that my improved sprinkling apparatus -be associated with such a supporting means. j

My sprinkling device per se embodies the provision of a tank 12 positioned upon'said platform 5 vand secured thereto through the medium of a desirable number of straps 13 this tank beine' formed with a filling openingle within which is positioned a closure Vplug 15, Figure 3. i

Adj acent the lower side of the tank 12 and I in the rear wall thereof is an opening 16 in alineinent with which is a rearwardly di-k rected pipe 17 this pipe being secured to the tank in communication with said openf ing through the medium of any desirable form of coupling. The said pipe 17 is in continuous relationship with another pipe.

18 secured to each other through the medium of a multi-way coupling 19 there being also associated with this coupling 19 a vertically kextending pipe 2O and a downwardly.

extending pipe 21. The pipe 20 is equipped adjacent its upper end with a compressed air inlet valve 22 as well as a pressure gauge23 the other pipe 21 being associated kwith a Vcontrol valve 24: through the medium of an front end within a bearing 28 within Said` tank l2 and upon the front wall ther-cot. The portion et this shaft 27 within the tank i5 is equipped with a desirable number ot agitating plates 29 which are preferably arranged in staggered relation to each other as clearly shown in Figure 3. The rearmost end of said shaft 27 is equipped with a crank handle 3G in convenient reach of the operator upon the seat l0 for enabling the shaft to be rotated and the Scrapers 29 consequently actuated to scrape the material that would settle to the bottom ot the tank therefrom.

Freely slidable in collars 3l formed upon the lower ends of metal hangers that are provided with a plurality of openings 33 whereby the same may be adjustably secured to the before mentioned platform 9 at opposite sides o't the seat l() and adjacent the 'front end thereof through the medium of bolts or other` suitable connections 34 is a transversely disposed relatively elongated pipe 35. 'E his pipe 35 as more clearly shown in Figure 2 is equipped centrally with a T- coupling 3S and at its opposite ends with eioow couplings 37. Pendant from each ot' these couplings is a short pipe section 38 that is in turn equipped at its lower end with a Ecoupling 39 secured to the opposite ends of which are elbow couplings 40 to which are in turn secured pendant flexible pipes 41. lVithin the lower ends of these riexible pipes Ll-l as shown in Figure 1l, ar sprinkler heads ll2 which are adjustably connected to each other through the medium of a pair or links adjustably secured together through the medium oi? a bolt and nut connection 44; it being obvious that each ot said links is provided with a plurality ot' openings l5 tor purposes of adjustment.

Having communication with the before mentioned transversely arranged pipe 35 is a forwardly extending short pipe section that carries at its opposite end a l'coupling i7 which is in communication with the beloro mentioned control valve 2a through the medium ot a flexible connection 48. EX- tending upwardly from said T-coupling Li7 is a pipe Li9 that is equipped at its upper end with a closure cap 50 it being noted in this connection that this pipe 49 affords a hand lever whereby said pipe 35 may be shifted laterally in opposite directions within the collars 3l formed upon the lower ends of said hangers 32 whereby the pairs of fluid discharge nozzles may be adjusted when desirable this pipe 49 also serving as an air trap.

The specific operation together with numerous advantages of a spraying machine of this character will be at once apparent to those skilled in the art, it being obvious that l have provided a machine that will meet with all ot the requirements for a successful commercial use.

Minor changes may be made within the invention without departing from the spirit and scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

in a plant spraying machine, a nozzle structure comprising a pipe, a Tsshaped titting connected with the pipe, elbow fittings connected with the ends of the T-shaped {itting, flexible pipe sections connected with the elbow fittings and disposed approXi mately parallel with each other, sprinkler heads connected with the flexible pipe sections, links connected at their outer ends *ith the sprinkler heads and having inner end portions which overlap each other horizontally and a pivot bolt for adjustably securing the overiapping portions of the links together, said pivot bolt being parallel with the sprinkler heads.

in testimony whereof l aiiiX my signature.
